| ↳ | android.database.ContentObservable

A specialization of `Observable` for `ContentObserver` that provides methods for sending notifications to a list of `ContentObserver` objects.

## Summary

### Inherited fields
From class `android.database.Observable`
`protected final ArrayList<T>` | `mObservers` The list of observers.

### Public constructors
`ContentObservable()`

### Public methods
`void` | `dispatchChange(boolean selfChange)` This method is deprecated. Use `dispatchChange(boolean, android.net.Uri)` instead.
`void` | `dispatchChange(boolean selfChange, Uri uri)` Invokes `ContentObserver#dispatchChange(boolean, Uri)` on each observer.
`void` | `notifyChange(boolean selfChange)` This method is deprecated. Use `dispatchChange(boolean)` instead.
`void` | `registerObserver(ContentObserver observer)` Adds an observer to the list.

### Inherited methods
From class `android.database.Observable`
`void` | `registerObserver(ContentObserver observer)` Adds an observer to the list.
`void` | `unregisterAll()` Remove all registered observers.
`void` | `unregisterObserver(ContentObserver observer)` Removes a previously registered observer.
From class `java.lang.Object`
`Object` | `clone()` Creates and returns a copy of this object.
`boolean` | `equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void` | `finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>` | `getClass()` Returns the runtime class of this `Object`.
`int` | `hashCode()` Returns a hash code value for the object.
`final void` | `notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void` | `notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String` | `toString()` Returns a string representation of the object.
`final void` | `wait(long timeout, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void` | `wait(long timeout)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void` | `wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

### dispatchChange

    public void dispatchChange (boolean selfChange,
                    Uri uri)

Invokes `ContentObserver#dispatchChange(boolean, Uri)` on each observer. Includes the changed content Uri when available.

If `selfChange` is true, only delivers the notification to the observer if it has indicated that it wants to receive self-change notifications by implementing `ContentObserver#deliverSelfNotifications` to return true.

Parameters
`selfChange` | `boolean`: True if this is a self-change notification.
`uri` | `Uri`: The Uri of the changed content, or null if unknown.

### notifyChange

    public void notifyChange (boolean selfChange)

This method is deprecated.
Use `dispatchChange(boolean)` instead.

Invokes `ContentObserver#onChange` on each observer.

Parameters
`selfChange` | `boolean`: True if this is a self-change notification.
